Abstract: Eight title compounds Ia~h were synthesized by nucleophilic substitution of alkyl dichloro phosphorate by sodium-4-(quinoxalyl-2-oxy)phenolate followed by reaction with secondary amines in polar organic solvent. Their structures were characterized by elemental analysis, IR,1H NMR,31P NMR, and MS measurements and their herbicidal activities were tested.

Key words: quinoxalyloxyphenylphosphoramidate, synthesis, herbicide
